Subject: [PATCH 07/38] lib/open: load default values for known configuration keys.
Date: Sat, 16 Jan 2021 13:03:35 -0400 [thread overview]
Message-ID: <20210116170406.842014-8-david@tethera.net> (raw)
In-Reply-To: <20210116170406.842014-1-david@tethera.net>
This emulates the behaviour of notmuch_config_open defined in the CLI,
in that it fills in default values if they are not otherwise defined.
